TYPE-WRITING MACHINE.-

SIECIFICATION forming-part of Letters Patent N 0'. 749,002, dated January 5, 1904.

Application filed March 9, 1899. Serial No. 708,424. (No model.)

To all whom it may concern.-

Be it known that I, OLUF TYBERG, a citizen of the United States, residing in the borough of Brooklyn, city of New York, State of New York,have invented certain new and useful Improvements in Type-WritingMachines, of which the followin is a specification.

In an application filed by me May 8, 1897, Serial No. 635,681, I have shown a broadly novel organization wherein a wheel continuously revolving about a normally stationary axis-has, when desired, imparted to it abodily motion in a direction opposite to that in which the impression side of the wheel is traveling. The resultant eifect of this momentary composite motion is that the character on the wheel selected to be printed from is momentarily maintained at the printingpoint.

The machine herein described operates upon the same general principle; and the present invention comprehends new and useful ways of controlling the operation of the continuously revolving wheel, taking impressions therefrom,and eifecting the required operations of a type-writing machine.

In another application filed by me March 9, 1899, Serial No. 708,423, I have shown a type-writing machine more nearly resembling that disclosed herein than does the machine disclosed in my application first above-mentioned, and in said second application I have shown and claimed, broadly or generically, certain parts of the organization disclosed in the present case.

In the accompanying drawings, Figure 1 is an elevation of the left-hand end of the machine; Fig. 2, a plan view thereof, partly in section, on the line 2 2 of Fig. 1, with the driver partly broken away; Fig. 3, a front elevation, partly in section, on the line 3 3 of Fig. 1; Fig. 4, a detail view showing the essential parts of the carriage-feed devices; Fig. 5, a similar view of the same parts in a difierent position. Figs. 6, 7, 8, r 9, and 10 are similar views showing in difierent positions a finger-key, a star or toothed wheel'carried thereby, a driver that operates the wheel, and a swinging lever or frame operated by the wheel to so control the type-Wheel as to maintain the selected character thereon momentarily at the printing-point.

tinuously-acting driver and as I prefer to use a rotary driver, I have shown a cylindrical driver 1, whose shaft or trunnions 2 2 have their hearings in the ends or vertical side plates 33 of the machine. This driver may be continuously rotated by any suitable motor located upon the stand of the machine and to'this end may be provided with a driving-pulley placed upon its right-hand end, as indicatedin Fig. 3. This driverisacammed, ribbed, or toothed driver and is shown as having a series of projections 4, extending spirally from one end to the other around its circumference. Mounted upon the left-hand end of the shaft or trunnion 2 of the driver is a rocking frame 3, having two parallel parts 6 6, extending toward the rear of the machine and in which the type-wheel shaft 7 has its bearings. The gear-wheel 8, keyed to the driver trunnion or shaft between the parts 6 6 of the rocking frame, meshes with a corresponding gear 9,keyed to the type-wheel shaft. As shown, these gears are of equal diameter, and the type-wheel shaft and the driver revolve at the same speed. The type-wheel 10 is, shown as having two series of characters thereon and as connected to the typewheel shaft by a spline or feather connection 11, which permits the wheel to slide axially to bring either series of characters thereon opposite the printing-point. One seriesthat to the right andconsisting merely, for illustrative purposes, of the Arabic num eralsis normally opposite the printing-point, and the wheel may be shifted endwise to the left, as

hereinafter described, to bring the other series of characters opposite the same point, this latterseries being shown merely for illustrative purposes as consisting of the Roman numerals. ,But ten characters in each series connected with a rock-shaft 17, mounted in hearings in the side or end plates of the machine. From this rock-shaft arms 18 extend toward the front of the machine in a plane below the type-wheel and driver and carry a transverse plate or bar 19. If new the bar 19 be momentarily raised, a movement would be imparted to the type-wheel, through the arm 16, link 15, arm 12 of the rocking-frame and side plates 6 6 of that frame, and such motion would be a downward one, the normal axis X of the type-wheel being carried down to the point Y, as indicated in Fig. 1. The rotation of the type-wheel being in the direction indicated by the arrow, this bodily movement of the axis of the wheel from X to Y is in a direction opposite to the rotation of the rear or impression side of the typewheel, and any character thereon selected to be printed from will for a moment be maintained at the printing-point, when an impression maybe taken therefrom. In the particular organization shown the movement of the rocking-frame that carries the type-wheel axis through the arc X Y also operates the hammer 14, through the link 13, to take an impression from the character then momentarily maintained at the printing-point. The means for effecting this behavior of the typewheel will now be described.

The key-levers 20 are respectively pivoted upon a cross-bar 21, and their movement is limited by upper and lower cross-plates 22 23. Each key-lever is maintained in its normal elevated position by a vertical plate-spring 24, formed near its end with a lateral wedge 25, that works against the correspondingly wedge-shaped end of the lever-that is to say, when the key is in the normal elevated position, as shown in Fig. 6, the lower inclined face of the spring rides upon the upper inclined face of the end of the lever and holds the outer end of the key-lever raised. When a key is depressed, the upper inclined face of the spring bears against the lower incline of the end of the lever and forces it upward to the limit of the movement of the lever until the parts are restored to the normal position, as will now be described.

Loosely mounted near the end of each keylever is a star-wheel 80, that shown having five teeth or projections arranged in suitable relation to the driver 1, rocking frame or plate 19, and fixed stop 26, all as shown in Fig. 6. If now the lever be depressed, as shown in Fig. 7, the angle formed by the inclined faces at its end rides past the corresponding angle of the spring 24, and the upper inclined face of the spring then acting upon the lower inclined face of the end of the lever completes the upward movement of the inner end of the lever and projects the star-wheel into the path of the corresponding projection 4 on the driver, as shown in Fig. 8. During this movement the star-wheel is prevented from turning in either direction by the end face of the transverse bar 19 and the fixed stop 26 and is presented in such relation to the driver that a radial line from the axis of the driver to the axis of the wheel bisects the space between the two teeth of the wheel contiguous to or then in cont-act with the plane circumferential face of the driver. The projection 4 on the driver now comes against one of the teeth of the star-wheel and partially rotates it, as seen in Fig. 9, the eifect being that the following tooth on the wheel comes against the under face of the transverse plate 19 and moves it upwardly, thus efiecting the traverse of the axis of the type-wheel through the arc X Y,thereby maintaining the character on the wheel corresponding to the key momentarily at the printing-point and also actuating the hammer to take an impression therefrom. At the same time the end of the tooth of the wheel against which the projection 4 on the driver is working is of necessity forced downward, as appears in Fig. 9, and the wedge-shaped end of the lever is carried below the wedge 25 of the spring. As the movement is being completed, as indicated in Fig. 10, the outer end of the finger'key rises, a tooth of the wheel comes against the fixed stop 26,and the transverse plate 19 falls behind the tooth that has lifted it and the parts again assume their normal positions, the front edge of the plate 19 and the fixed stop 26 preventing the rotation of the wheel in either direction. A spring 27, having one end connected to theframe and the other to the pendent arm 12 of the rocking frame carrying the type-wheel, returns the rockingframe and associated parts and the transverse plate 19 to their normal positions which is determined by a stop 28 on the frame against which the arm 12 of the rocking frame abuts.

In the organization shown, since the typewheel and driver rotate at the same speed, there is upon the driver but one projection, tooth, or cam for each character in either series of characters on the type-wheel, and of course the projections are radially disposed, corresponding with the radial disposition of the characters on the wheel. Any other appropriate relative speeds of the driver and type-wheel may of course be adopted and the projections on the driver be correspondingly arranged. Thus if the type-wheel made two revolutions to one of the driver there would be two projections at opposite points on the driver for each character in either series of characters on the type-wheel. The typewheel may be shifted endwise upon its shaft to bring either series of characters opposite the printing-point in the following manner.

A shifting-key 29 is shown as an arm projecting horizontally from a rock-shaft 30,having a spring 31, tending to retain it in normal position. This shaft rocks in bearings 32 32 and carries at its rear end an upwardlyextending arm 33, that lies in an annular groove or channel 34, formed in the sleeve of carrying the roll 36, may be of any ordinary construction. As shown, it consists of a rectangular frame having a rod 37, running in a guide 38 in a bracket 39, extending rear wardly and upwardly at the back of the frame and about opposite the type-wheel.

It also has a vertical plate 40, runningin the grooves of rolls 41, mounted on a transverse bar 42, extending across the rear of the frame.

The rack 43 is vertically arranged at the front edge of the carriage. The paper is indicated by Z and is passed down into a curved holder 44, mounted on and arranged below the carriage, and passes upward as lines are successively printed between the. roller 36 and the front vertical edge 45 of the holder, which acts as a spring bearing against the face of the roll, the paper being fed upwardly in the construction shown by the manual turning of the roll 36. pawl 46 is pivoted in the end of a vertical arm 47, extending upwardly from a rockshaft 48, from which an arm 49 extends to the opposite end of the machine, where it is pivotally connected with a vertical rod 50, connected to the arm 51 of a plate capable of rocking on the trunnion or end of the On this trunnion or shaft there is'a toothed or ratchet wheel 53, mounted to turn with it, and on the rocking plate 52 is pivoted a three-armed latch 54, one arm of which, 55, is formed witha hook and is adapted to engage the teeth of the wheel 53. The other arm, 56, of the latch when in the normal position extends upwardly into the path of a pin 57, carried at the end of an arm 58, extending upwardly from the rock-shaft 17. The other arm, 59, of the latch is adapted to be caught by a catch 60, pivoted on the plate 52. A stop 61 on the frame limits the movement of the rocking plate 52, and a stop 62 on bhf plate 52 limits the movement of the latch-a .n 55 away from the wheel. As seen in Fig. 2,a spring 63 is applied to the pivot of the latch 54 and acts to hold its arm 55 away from the wheel 53. Similarly a spring 64-is applied to the pivot of the catch and tends normally to move its upper or hooked end toward the arm 59 of the latch 54. When the tooth of a star-wheel carried by a finger-key acts'upon the plate'19 to rock the shaft 17, and thus, as described,

move the axis of the type-wheel through the arc X Y, the desired character-is momentarily maintained at the printing-point'and an impression taken therefrom. During this time the arm 58,projecting upwardly from the shaft 17, moves rearwardly,carrying with it the arm 56 of the latch 54 and moving its catch-arm into the path of a tooth of the wheel 53, which is approaching it, and causing the third arm of the latch to be engaged and locked by the catch 60. After the impression has been taken The feedingthe tooth onrthe wheel comes against the arm 55 of the latch and carries itand the plate 52 around with it, as shown .in Fig. 5, thereby raising the rod or arm 50 and rocking the arm 47 toward the left, the pawl 46 thereon in engagement with the carriage-rack then advancing the carriage one step or space. When the desired extent of movement of these parts has been obtained, the inclined tail or end 65 of the catch 60 comes against a tripping-block 66, mounted on the side plate of the machine. The catch is thereby caused to move out of engagement with the latch 54, which by the action of its spring returns to its normal position, and the plate 52, and this plate, rod 50, arm 49, and rock-shaft 48, &c., are returned to normal position by the reaction of a spring 66, Fig. 1, appliedvto the rock-shaft.

I have illustrated in the drawings only What seems requisite to aclear comprehension of the invention and have omitted immaterial parts. trolling the carriage has not been shown nor a line-spacing mechanism, as these may all be of any ordinary or suitable kind. Similarly no space-key is shown. The spacing may be accomplished in any suitable way, a

special key being of course provided. The arrangementmay be'such as that shown in my second application, Serial No. 708,423, filed March 9, 1899, above referred to, and which shows a type-writing machine of the general character of the machine herein dis closed.
